If you have any experience in such a setup (Windows on a primary partition and Linux/Grub2 on a logical partition) and you could give me some advice to help me find out what I’ve done wrong, I would greatly appreciate it.

#Grldr.mbr commands windows 7#
When Linux is installed on a primary partition everything works fine, but when Linux is installed on a logical partition Windows bootloader (BOOTMGR) is unable to chainload to Grub2, it can load Windows 7 but not Linux (the system just restarts as if BOOTMGR didn’t see where Grub2 was). However, in my case it simply doesn’t work. So he is saying that it is perfectly possible to get a dual-boot such as the one described in your article when Linux is installed on a logical partition. “Some documents state that the partition being loaded by the Win boot-loader must be a primary partition but I have used this without problem on an extended partition. Your article has been quoted as a source in a wiki page for Archlinux : I just have one question though, I hope you will be able to help me. Now it should you so much for this article, it helped me a lot ! Take your Linux menu.lst and edit it under Linux. The appropriate menu.lst could look like this:Ĭolor blue/green yellow/red white/magenta white/magenta Copy it to the the Windows root directory, usually C.

The entry with the actual id returned from the previous command.įor a first trial you may use the menu.lst from the GRUB4DOS package. Now, use bcdedit for the entry in the windows 7 boot manager:īcdedit /create /d “Linux” /application bootsector GRB4DOS is a powerfull package but you only need two programs of it – grldr and grldr.mbrįrom this package copy grldr and grldr.mbr to the Windows root directory, usually C.

In this entry you have to call GRUB4DOS instead of GRUB within linux.bin You can use bcdedit to build an entry in the windows 7 boot manager. I have found a solution to start Linux by the Windows 7 boot manager if Windows and Linux are on different hard disks. When complete, exit out of the Disk Management tool and reboot the system.

Right-click on the Windows 7 volume (C:) and selected “Shrink Volume.” Then enter the amount of space (in Megabytes) that the partition should shrink (which in turn becomes the amount of space available to install our Linux distribution), which in our example is 48000 Megabytes (48 Gigabytes), then select “Shrink” (See Figure 1). Windows 7: ~100MB (Windows 7 boot loader) For our 320 GB disk example, we’ll use the following partition layout: You’ll need to determine how much space you want to allocate to each of these additional partitions based on your requirements and disk size. We’ll also create a small FAT32 partition for sharing data between Windows 7 and Ubuntu. When finished, we’ll have five partitions in total: the two Windows 7-related partitions just mentioned, and ones for the Ubuntu operating system and Linux swap. You’ll notice that Windows 7 currently occupies all of the existing disk space using two primary partitions: one small boot partition the other for the operating system. The Disk Management tool can be accessed by using Win+r and entering the command diskmgmt.msc. While you can use third-party applications like GParted, I found Windows 7’s own Disk Management tool to be the most efficient method for accomplishing this task. The first thing that we need to do is reduce the size of the existing Windows 7 partition.

Oh…, and while I’ve never encountered a situation where the Windows 7 Disk Management tool destroyed existing disk data, make sure you backup any critical files before you proceed.
#Grldr.mbr commands software#
The software versions used in this post were as follows: All steps involved assume you have a functioning CD drive (or USB drive if you’d prefer) that the system can boot from. We’ll then use BCDedit to add a Windows boot menu option for Ubuntu. We’ll reduce the size of the partition containing the Windows 7 operating system and re-partition the remaining unallocated disk space in order to install the Linux distribution Ubuntu. To help explain the steps involved, we’ll use an 320 GB SATA hard drive with Windows 7 already installed. Configuring BCDEdit to recognize and boot a Linux distribution located on a second physical hard drive is beyond the scope of this post. The steps described in this post assume that Windows 7 and the Linux distribution will occupy the same physical hard drive.

This post will describe how to use the Window 7 boot configuration data editor (BCDEdit) to configure a Windows 7 system that can boot to Windows 7 or a Linux distribution.
